Eh...it's just my opinion. I'm old school in that way.
For me, YouTube is for watching clips of TV shows, concerts, etc. I have no interest in watching original content there at all.
It's just unappealing to me. (Even that name, Pewdiepie or whatever, repells me. Just has a hipster, millennial vibe that annoys me.)
Grace Helbig? No idea who that is. (I dislike E! in general) I don't care where someone gets their start. They become relevant (if at all) to me when they hit TV or the theater.
Otherwise....I'll pass.
